The best way to make use of solar energy is to set up device grouping in the control panel.
Empyrion using solar panels.
Generators do still need a fuel tank and battery power overflow does not get stored as fuel.
Add non essential devices or those which use large amounts of power to a generator power group.
The capacitor solar is a base device used mainly to store and distribute power produced by solar panel blocks.
Panel placement panel size weather and time of day all affect the output of solar panels.
Each capacitor can hold a finite amount of energy meaning that adding multiple to your base will increase the maximum amount of power that can be stored.
In addition to storing solar power the capacitors can also burn fuel stored in tanks in the base making them a feasible alternative to generators.
So if your panels are enough you won t use any fuel.
Generally love thy survival constructor.
If you read nothing else.
Get at least a dozen solar panels up and turn off things not in use and one should see batteries actually charging.
And 2 or even 4 small solar panels isn t enough.
Solar panel blocks are blocks used as an alternate source of power.
Let s talk about energy efficiency.
There are no infinite sources in empyrion other than the trusty survival constructor and water so not dying and spending most of your time not just mining is pretty much about using energy efficiently.
Next add a switch to power on off the items which you want to use generator power for.
It must be paired with the capacitor solar to store the energy absorbed by the blocks.
Solar is used first then generator power.
So if your solar output is not more than your consumption your batteries will never charge.
Having a backup generator is probably a good idea.
For more power add more panels or replace your small solar panels with regular solar panels.
